Has anyone else noticed the growing number of used LEAFs offered for sale with 10, 11, and 12 capacity bars? This is fraudulent activity and California authorities may want to investigate.Thank you to anyone that responds with his/her thoughts on this matter.

It is only fraudulent activity if the BMS is purposely reset to hide the true state of the battery. There are also several software updates applied by Nissan dealers that reset the BMS as part of the update. If the car is showing less than 12 bars, then it is not likely that it has been reset. The AHr reading stays constant, even with a reset, so checking with LeafSpy is the only way to know for sure on a 12 bar car.

Big assumption. Cars from some places don't degrade rapidly, and a number of those cars will have had battery replacements, so those cars are probably legitimate. However, I do think that battery status (age, capacity) may ultimately need to be disclosed in a way similar to odometer readings.

If so then I don't see any harm in owners with paid batteries doing it.

No extra range is gained since the battery only has whatever capacity it has. The charging circuity will still limit the current flow in/out of the battery and the max/min voltage it allows the battery to reach. Resetting the BMS does nothing except corrupt the firmware that calculates and indicates the available battery capacity.
